COnsole Newsreader and Emailer

Cone is a text-based mail client. Cone seamlessly handles multiple
POP3, IMAP accounts, and local mail folders. Cone is also a simple
newsreader. Cone's interface is foolproof enough to be used by
inexperienced users, but it also offers advanced features for power
users.

Beyond others cone has support for PGP, GPG, UTF-8, IMAP, POP3,
incoming HTML mails, external viewers, NNTP, SOCKS 5, SSL/TLS, SASL,
LDAP and IMAP based address books, remote storable configuration,
multiple accounts, tagging mails with several different flags, and
SMAP (Simple Mail Access Protocol, a new IMAP and POP3 replacement
developed by the Courier guys and supported by the Courier
development versions).
